Jumper Settings/Clear BIOS Password Procedures
1. Remove the DIMM cover and the lower DDR2 memory module, then find out the G96 position on the main board. Please just the lower DDR2 memory module, you will need the upper DDR2 memory module to boot up the system. (You should tear off the mylar to see G96). 
2. Use a tweezers or a screwdriver to short the G96 pad and remain the short status. 
3. Power on the system until POST is completed. Then you can release the tweezers or screwdriver. The BIOS password should be cleared after these steps.
